Factors Affecting Performance [Text Block]
Management's discussion of fund performance
The fund’s Class A shares gained 18.34% for the year ended June 30, 2025. That result compares with a 17.72% gain for the MSCI ACWI (All Country World Index) ex USA. For information on returns for additional periods, including the fund lifetime, please refer to
capitalgroup.com/mutual-fund-returns-A
.
What factors influenced results
International stocks advanced in a period marked by erratic trade policy and signs of
slowing
growth. Europe saw moderate growth driven by resilient domestic demand and easing inflation despite global trade tensions. Germany announced fiscal reforms, including plans to increase spending on defense and infrastructure projects, which are expected to boost the country’s economy and potentially have broader positive implications for Europe. The U.K. showed early signs of recovery, though persistent inflation limited overall momentum. Japan’s growth slowed, hindered by weak consumer spending and declining export demand. Among emerging markets, China’s growth was supported by targeted stimulus and a rebound in exports, while India’s economy remained resilient despite slower growth amid global headwinds.
Overall, most sectors added to the fund’s positive results, with financials and utilities particularly additive. Likewise, holdings in industrials, communication services and consumer staples saw returns surpassing those of the overall portfolio. From a geographic perspective, shares of companies based in the eurozone and the United Kingdom contributed positively to absolute returns.
On the contrary, holdings in the health care sector saw negative returns during the period. Also, investments in companies based in European countries outside the eurozone were negative, and Japan holdings detracted from the broader portfolio’s return while remaining positive.

Likewise, holdings in industrials, communication services and consumer staples saw returns surpassing those of the overall portfolio. From a geographic perspective, shares of companies based in the eurozone and the United Kingdom contributed positively to absolute returns.
On the contrary, holdings in the health care sector saw negative returns during the period. Also, investments in companies based in European countries outside the eurozone were negative, and Japan holdings detracted from the broader portfolio’s return while remaining positive.

Factors Affecting Performance [Text Block]
Management's discussion of fund performance
The fund’s Class 529-C shares gained 17.42% for the year ended June 30, 2025. That result compares with a 17.72% gain for the MSCI ACWI (All Country World Index) ex USA. For information on returns for additional periods, including the fund lifetime, please refer to
capitalgroup.com/mutual-fund-returns-529C
.
What factors influenced results
International stocks advanced in a period marked by erratic trade policy and signs of slowing growth. Europe saw moderate growth driven by resilient domestic demand and easing inflation despite global trade tensions. Germany announced fiscal reforms, including plans to increase spending on defense and infrastructure projects, which are expected to boost the country’s economy and potentially have broader positive implications for Europe. The U.K. showed early signs of recovery, though persistent inflation limited overall momentum. Japan’s growth slowed, hindered by weak consumer spending and declining export demand. Among emerging markets, China’s growth was supported by targeted stimulus and a rebound in exports, while India’s economy remained resilient despite slower growth amid global headwinds.
Overall, most sectors added to the fund’s positive results, with financials and utilities particularly additive. Likewise, holdings in industrials, communication services and consumer staples saw returns surpassing those of the overall portfolio. From a geographic perspective, shares of companies based in the eurozone and the United Kingdom contributed positively to absolute returns.
On the contrary, holdings in the health care sector saw negative returns during the period. Also, investments in companies based in European countries outside the eurozone were negative, and Japan holdings detracted from the broader portfolio’s return while remaining positive.

Factors Affecting Performance [Text Block]
Management's discussion of fund performance
The fund’s Class R-1 shares gained 17.44% for the year ended June 30, 2025. That result compares with a 17.72% gain for the MSCI ACWI (All Country World Index) ex USA. For information on returns for additional periods, including the fund lifetime, please refer to

.
What factors influenced results
International stocks advanced in a period marked by erratic trade policy and signs of slowing growth. Europe saw moderate growth driven by resilient domestic demand and easing inflation despite global trade tensions. Germany announced fiscal reforms, including plans to increase spending on defense and infrastructure projects, which are expected to boost the country’s economy and potentially have broader positive implications for Europe. The U.K. showed early signs of recovery, though persistent inflation limited overall momentum. Japan’s growth slowed, hindered by weak consumer spending and declining export demand. Among emerging markets, China’s growth was supported by targeted stimulus and a rebound in exports, while India’s economy remained resilient despite slower growth amid global headwinds.
Overall, most sectors added to the fund’s positive results, with financials and utilities particularly additive. Likewise, holdings in industrials, communication services and consumer staples saw returns surpassing those of the overall portfolio. From a geographic perspective, shares of companies based in the eurozone and the United Kingdom contributed positively to absolute returns.
On the contrary, holdings in the health care sector saw negative returns during the period. Also, investments in companies based in European countries outside the eurozone were negative, and Japan holdings detracted from the broader portfolio’s return while remaining positive.

What factors influenced results
International stocks advanced in a period marked by erratic trade policy and signs of slowing growth. Europe saw moderate growth driven by resilient domestic demand and easing inflation despite global trade tensions. Germany announced fiscal reforms, including plans to increase spending on defense and infrastructure projects, which are expected to boost the country’s economy and potentially have broader positive implications for Europe. The U.K. showed early signs of recovery, though persistent inflation limited overall momentum. Japan’s growth slowed, hindered by weak consumer spending and declining export demand. Among emerging markets, China’s growth was supported by targeted stimulus and a rebound in exports, while India’s economy remained resilient despite slower growth amid global headwinds.
Overall, most sectors added to the fund’s positive results, with financials and utilities particularly additive. Likewise, holdings in industrials, communication services and consumer staples saw returns surpassing those of the overall portfolio. From a geographic perspective, shares of companies based in the eurozone and the United Kingdom contributed positively to absolute returns.
On the contrary, holdings in the health care sector saw negative returns during the period. Also, investments in companies based in European countries outside the eurozone were negative, and Japan holdings detracted from the broader portfolio’s return while remaining positive.
